Aura Herbals is a Polish manufacturer of dietary supplements, operating in one of the most demanding industries in the context of SEO - YMYL (Your Money Your Life, i.e. industries related to health and money). The company has been building its position for years, offering products based on natural ingredients and supporting consumer education through guidance content.

A team was responsible for the project on the part of our partner Aura Herbals, whose professionalism and hard work have significantly influenced the current success of the project:

  • Adrian Tkaczyk - Marketing and Product Director
  • Nina Wawryszuk - Editor-in-Chief, SEO & Content Marketing
  • Ada Renk - Marketing Manager
  • Sebastian Hoffman - IT Manager

A word of introduction

The campaign for AuraHerbals.co.uk is a perfect example of the kind of results that cooperation with an SEO agency can lead to if both parties have 100% of trust in each other.

A lot of analysis and strategy considerations, out-of-the-box „plays” and, above all, confidence in the strategy are key to the success of this campaign. Thanks to Adrian and Nina from Aura Herbals, we were able to show what steps we sometimes have to go to in order for the website to grow organically in the Google results.

They were not typical activities, as migrations, sharp cuts and agreeing to remove nearly 200 articles as part of content pruning, rebuilding the site or budgeting for PR SEO activities are difficult decisions for the client.

However, in this campaign they have translated into a reversal of the negative trend, and at the moment to the number 1 position among competitors looking at visibility in AIO.

Objectives of cooperation

Exit of the HCU filter and reversal of the downward trend

Following the Helpful Content Update (HCU), Google's September 2023 algorithm update, we wanted to get out of the downward trend in terms of visibility in Google's organic results.

Rebuilding and developing visibility in TOP3

The main goal was to rebuild pre-downturn visibility and a strong focus on the business aspects of SEO. We worked on category pages, product pages and business support pages.

Increasing organic traffic and attracting new sources of traffic

We started to pay attention to new traffic sources like Discover. The other non-obvious source of traffic we have taken into account is the parasite sub-sites, where we have used PR SEO activities.

Starting situation

Analyses while still at the bid stage led us to the September 2023 HCU (Google Helpful Content Update), when the site began to lose visibility and thus traffic. This was a signal that we needed to focus heavily on analysis in the context of the content within the site and implement additional measures to stop the decline and return to an upward trend. 

decrease in HCU

Main identified issues within the site:

  • healthlabs.care - phrase: healthlabs - 49,500 wysz. Months.
  • olimpstore.co.uk - phrase: olimp - 40,500 wysz. month.
  • aliness.co.uk - phrase: aliness - 18,100 wysz. month.
  • allnutrition.co.uk - phrase: allnutrition - 18,100 wysz. month.
  • ostrovit.com - phrase: ostrovit - 18,100 wysz. month.
  • primabiotic.co.uk - phrase: primabiotic - 14,800 wysz. Months.
  • auraherbals.co.uk - phrase: aura herbals - 4,400 wysz. Monthly.
  • Natu.Care - Phrase: natu care - 720 wysz. Months

Description of activities by the project supervisor

STAGE I (05.2024 - 08.2024) - foundations and migration

Migration of the shop (08.2024) from the subdomain sklep.auraherbals.co.uk to the main site. Before the shop migration, products were added in the main domain without the possibility to purchase with a redirect to the shop subdomain, where only the product could be purchased.

The aim of the migration was to unify the site and operate only under the main domain. The migration completed with subtle drops in visibility and traffic when considering both the visibility of the shop and the main site together. 

decrease in HCU

There was a lot of keyword phrase overlap between the main domain and the subdomain, and we decided to merge the subdomains through content merge and a 301 redirect map. The articles published on the blog and the shop were very similar, so we didn't expect increases after the content merge. We just wanted to unify the actions so that the algorithm did not have to choose one result or the other within the same domain.

During the migration of the website, we rebuilt the graphic design of the entire website. In particular, we focused on the framework of advice posts, categories and products that are particularly important for SEO. On the blog pages, we focused on providing Google with all the most important information „above the fold”, i.e. as high up on the page as possible. We already had AI Overviews (AIO) in the back of our minds and were planning specific solutions to make the most of its possibilities.

We created many new categories and optimised all of them for key phrases. During the migration, we merged the categories from the subdomain and the main domain.

When analysing the site in search of the cause of the drops, we came across the „Lexicon”, which it turned out was the main reason for the drops. This is a guide section that described the ingredients contained in Aura Herbals products. The articles were optimised for the phrases „properties / use”. The content in this section was outdated and often published more than 2 years earlier. They lacked proper semantics, did not cover the intention of the article topic and did not cover user needs.

Together with Aura Herbals, we selected a number of key themes for which we applied a silo strategy. We took into account the semantics of the themes and the nesting within the thematic structure. Here, we cannot forget the aforementioned editor-in-chief Nina, who understood our guidelines perfectly and was able to implement them while maintaining a very high level of content. Such partners are hard to find 🕯️.

We prepared guidelines that helped to develop business-relevant blog articles for Direct Answer. We carried out numerous optimisation tests, resulting in optimisation paths that were developed to gain high DA positions.

STAGE II (09.2024 - present) - trend reversal and development

During the content pruning, we removed 190 of the 580 articles that were running on the site at the time. These were not siloed to the mainstream theme of the site, so we decided to remove them and leave them with a 404. At the same time, we made sure they were not linked internally in any way so as not to create orphan pages. Hard reset ⏻️

We analysed the composition of all Aura Herbals products. We extracted all the ingredients and verified the potential for key phrases such as „*ingredient* properties”. We cross-referenced the results with all the articles functioning in the lexicon in order to decide which ones could stay and which ones to write from scratch or just robustly develop 🖋️

Example of migrated article “Vitamin A” 4 weeks before and after migration (migration date 4 February):

Vitamin A - 4 weeks before and after migration - case Aura Herbals

The article “Artichoke” was migrated on the same day:

Artichoke - 4 weeks before and after migration - Aura Herbals case

We planned the process of migrating valuable articles from the lexicon to the advice section. We wrote all of them taking into account the recommendations we had established. We hoped that Google would quickly forget about the low-quality content spotted by the Helpful Content Update. For this we also used the Ingredient Base we mentioned in the previous section.

During the campaign, we use the parasite technique, which involves publishing high-quality articles on high authority sites. In such a situation, there is a good chance that such an article will gain high positions in search results. Thus, we gained another source of traffic and potential conversions, e.g. the purchase of an article on poradnikzdrowie.pl (article no longer available), where, for example, on 1 December it was visible on the 6th position for the phrase “berberine which is the best” ( 600 wysz. mies.) and was able to break through in a few days and generate quite nice traffic to the site, and below is an example of how it looked in Ahrefs:

Buying parasite items - case SEO Aura Herbals

The success of parasite SEO convinced our partner to implement an additional budget for the acquisition of PR articles.

During optimisation, we were aware of the upcoming AI Overviews. By optimising existing content, we were able to achieve excellent results. Below is an example that you can see if you type in the phrase “berberine opinion of doctors”

Such a category is both a category and an advice post. The main purpose of this is to try to build visibility for general informational words, i.e. our pillar page. Linking from breadcrumbs and the main menu is to further influence the power of this sub-page, which we want to treat as a category according to the logic of building the site structure.

An example of such a category is “Colloidal silver”. At the moment there are not many such categories, but we plan to work on developing this strategy. 

Results of actions

Target: Exit the HCU filter and reverse the downward trend

We have reversed the downward trend in TOP 3 and as of 20.05.2025 (date during the creation of the case study for the semKRK competition) the number of phrases was higher than after HCU. We are still a little short of the visibility record. However, we are currently focusing on building visibility in line with the client's business directions.

Below is the data from the Ahrefs tool, where one can see a significant increase in TOP3 (130%) and a slightly more modest but much better-targeted increase in TOP10 (14%). It is worth noting that the graph is characterised by an almost uninterrupted upward trend.

Since January 2025 we have had an upward trend of several months and we recognise that since then the final HCU of September 2023 has „let go” and we have been able to get out of the filter.

Objective: „Increasing organic traffic and attracting new sources of traffic”.”

In order not to rely solely on estimates, we also present the increase in organic traffic across the domain.

Organic traffic 01.01-2025 - 30.04.2025 vs. 01.01-2024 - 30.04.2024 - is 60% higher (graphical data prepared during case study creation)

Traffic in the blog section over the same period also shot into space 🚀

movement blog

By the way, we managed to generate „some” traffic from Google Discover 🔍

Each additional entry from sponsored articles is always an additional value to the client's invested money. which strongly support the website's SEO. 

Translating actions into visibility in the AIO

A study we conducted showed that our content strategy translated into the highest visibility in AIOs among our competitors. We are now continuing the upward trend and gaining more and more visibility in AIOs and in LLMs. We have already created action patters that allow our clients to gain more and more high positions, both in AIOs and LLMs.

Customer comments

„The level of commitment and expertise that Kamil Brzozowski and his team have brought to the project has surpassed my previous experience of working with external partners. What sets Kamil apart is his proactivity - he does not wait for tasks, but initiates actions himself, proposes bold, strategic moves and takes responsibility for them.

The results described in this case study, i.e. a full reversal of the negative trend and a dynamic rebuilding of visibility, speak for themselves. Very importantly for us, Kamil was also able to perfectly transfer his knowledge and engage our internal team, creating a true synergy. This is partnership at its best.”

The best testament to working with Kamil on SEO activities is not only the impressive numbers, growth bars and green colour in Excel, but also my own skills that I have acquired or strengthened with him. My knowledge and understanding of SEO has increased significantly, so that I create even more quality content that not only attracts but also educates clients. I would highly recommend Kamil to work with him - he has a wealth of knowledge and knows how to communicate it perfectly.
